Firstly this is not a book on science, it is on mysticism, and sadly like most of this forumla it gets an awful lot wrong. Check out the film's reviews for a more honest cross section of views. If your into pseudo-science, philosophy or mysticism you'll love this as it is a pretty well thought out book. Personally I think twisting and altering science to a belief is a dangerous thing to do.
Anyway please do not get this book and think you will learn anything that you could say to a qualified physicist. If you know any of the "scientific" subject matter covered this will frustrate the hell out of you.
